The term 4G stands for the fourth generation of broadband Internet access technology in the mobile industry. It replaces 3G, and it offers several significant improvements over 3G and older technologies. A 4G connection offers faster Web browsing by providing data speeds that are four times faster than 3G. A 4G connection allows communications speeds up to 100 megabits per second, while 3G is limited to 7.2 megabits per second. Provided the data coverage is good, Web pages are less prone to timing out as they do with 3G.

Technical advances in Internet technology allow 4G to provide a more reliable signal and a wider range of coverage than older technologies. With a more reliable signal comes significant improvements in download speeds, improved quality of video and music streaming, more reliable Internet calling and improved voice-over Internet. The protocols used to implement security with 4G are among the most advanced in the wireless industry, and they guarantee near-total privacy and security. The benefits of enhanced safety and privacy are clear to businesses and organizations that deal with storing and communicating sensitive information on their mobile devices.
